摘要: 为探究复合盐碱胁迫下蚯蚓粪对高粱(Sorghum bicolor)生理生化特性及土壤改良作用的影响,本研究设置了4个复合盐碱浓度梯度(0%, 0.2%, 0.4%, 0.6%),同时开展盆栽试验并施加蚯蚓粪处理。结果表明,施加蚯蚓粪显著促进盐碱胁迫下高粱的生长,表现为株高、叶面积、存活率、苗鲜重、根鲜重及地上生物量等指标显著提高。与对照组相比,蚯蚓粪显著增强超氧化物歧化酶、过氧化物酶、过氧化氢酶和谷胱甘肽还原酶的活性,提高蛋白质、总叶绿素、可溶性糖及脯氨酸含量,降低丙二醛积累,有效缓解盐碱胁迫造成的氧化损伤。同时,蚯蚓粪显著降低土壤含盐量和pH值,提高有机质、速效磷和硝态氮含量。综上,蚯蚓粪通过改善土壤养分与理化特性,促进高粱生长、增强抗逆性,对盐碱土壤改良及盐碱地高效利用具有重要意义。

Abstract: In order to explore the effects of vermicompost on physiological and biochemical characteristics of sorghum (Sorghum bicolor) and soil improvement under compound saline-alkali stress, four compound saline-alkali concentration gradients (0 %, 0.2 %, 0.4 %, 0.6 %) were set up in this study. Pot experiments were carried out and vermicompost treatment was applied. The results showed that the application of earthworm manure significantly promoted the growth of sorghum under saline-alkali stress, which was manifested by significant increase in plant height, leaf area, survival rate, seedling fresh weight, root fresh weight and aboveground biomass. Compared with the control group, vermicompost significantly enhanced the activities of superoxide dismutase, peroxidase, catalase and glutathione reductase, increased the contents of protein, total chlorophyll, soluble sugar and proline, reduced the accumulation of malondialdehyde, and effectively alleviated the oxidative damage caused by saline-alkali stress. At the same time, vermicompost significantly reduced soil salt content and pH value, and increased organic matter, available phosphorus and nitrate nitrogen content. In summary, earthworm manure can promote the growth of sorghum and enhance stress resistance by improving soil nutrients and physical and chemical properties, which is of great significance for the improvement of saline-alkali soil and the efficient utilization of saline-alkali land.
